Temperatures have warmed above freezing for the first time in five days across much of the Willamette Valley this afternoon.
But the sky is gradually clearing from north to south and that means we'll be back below freezing in the overnight hours. With the clearing, fog is likely to form in parts of the valley. Combined with the below freezing temperatures, the fog may freeze on roads and other surfaces making for some slick spots overnight and in the morning.
Wednesday will be dry and partly sunny after the morning fog.
Rain returns Thursday, and it may begin as freezing rain in the valleys and especially in the Gorge. It should warm above freezing Thursday night, and by Friday the Arctic retreat will be complete.
The weekend brings partly sunny weather and a little light rain Saturday night and Sunday morning, with temperatures staying above freezing.
